Grounding an outlet refers to the process of creating a low-resistance path to the ground for electrical current. This is typically achieved by connecting a bare copper wire from the outlet’s ground terminal to a ground rod driven into the earth.
Grounding is essential for safety, as it provides a path for excess electrical current to escape in the event of a fault, preventing it from traveling through unintended paths, such as through a person’s body. Proper grounding also helps to protect against electrical surges and can improve the overall performance and reliability of electrical systems.
